Embodiment Construction

[0047] At present, the SIM card switching method of multi-card single standby is usually: when the network of the currently used SIM card is abnormal, switch to the standby SIM card.

[0048] However, such a single judgment condition switching method often results in meaningless switching. Here, the meaningless switching means that when switching to another SIM card, the system detects that the other SIM card does not meet the usage conditions, so when the previously used SIM card does not resume service, the system will Switch back and forth between the two SIM cards. Insignificant switching may exist in many scenarios, for example: it is difficult to access the base station in tunnels, valleys, etc. At this time, even switching SIM cards is usually meaningless. If no corresponding switching condition is set, the SIM card will be switched repeatedly, resulting in meaningless switching, thereby wasting resources. For another example, if the switched SIM card cannot access th...

Abstract

The invention discloses an SIM card switching method and an SIM card switching device, applied to mobile equipment including a data communication module which is connected with one of two or more SIMcards via a switching module. The method comprises the steps of judging whether the SIM card needs to be switched according to a preset environment condition, when an SIM card switching condition is triggered, wherein the environment condition comprises a terrain environment condition and / or base station environment condition; when it determines that the SIM card needs to be switched, noticing theswitching module to switch the SIM card, thus allowing the data communication module to be connected with the switched SIM card. According to the technical scheme of the method and the device, available switching between the SIM cards can be achieved, waste of resources caused by insignificant switching is avoided, great increase of cost of mobile equipment is not needed, and low cost and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a SIM card switching method and device. Background technique [0002] In the prior art, many mobile devices support the insertion of multiple SIM cards (that is, multiple cards), but the settings of the data communication module (usually including a baseband chip and a radio frequency chip) are not the same, and usually support a single SIM card according to the number of radio frequency chips. Standby (one RF chip) and multi-standby (multiple RF chips). [0003] Multi-card multi-standby undoubtedly increases equipment costs, and multi-card single-standby requires the selection of a suitable SIM card switching method. Contents of the invention [0004] In order to at least partly solve the above problems, the present invention provides a SIM card switching method and device. [0005] According to one aspect of the present invention, a method for switching SIM cards...
